3 Claims.

This invention relates to a therapeutic Vibrator and it consists in theconstructions, arrangements and combinations herein described andclaimed.

It is a particular object of the invention to provide an unbalancedrotor for a vibrator device so as to provide an uneven and lasting shockimpulse to the portion of a body undergoing treatment, the impulse beingdiverted to greater areas of the body.

It is also an object of the invention to provide a vibrator rotorwherein a pair of weight members are disposed at rights to each other,of equal size and of the same cross sectional area whereby underrotation an even force will be transmitted to that portion of the bodyundergoing treatment.

It is a still further object of the invention to provide a novelconstruction of housing for a vibrator unit adapting the device to thepositioned upon practically all portions of the body of a person andbeing constructed of a material which will readily transmit thevibratory impulses to the body.

Additional objects, advantages and features of invention will beapparent from the following description, considered in conjunction withthe accompanying drawing, wherein Figure 1 is a perspective view of avibrator constructed in accordance with the invention.

Figure 2 is an end elevation of the vibratorj-with a portion of the wallbroken away, illustrating the mounting of the vibrating unit.

Figure 3 is an end View of the vibrator with a portion of the wallbroken away, illustrating the relation of the rotor with respect to thevibrator unit.

Figure 4 is a perspective view of the rotor detached from the vibratorunit.

Figure 5 is a rear elevation, and

Figure 6 is a side elevation of the rotor.

There is illustrated a vibrator generally indicated by the referencecharacter l0, which as shown in Figure 2, comprises an upright resonantwooden wall ll upon one face of which there is mounted a vibrator unit[2. In the present instance, a pair of headed bolts 13 are secured inthe wall 11 projecting therethrough and rigidly engaged in the frame ofthe vibrator unit.

To respective end edges of the wall I I resonant wooden side walls 14are secured as at 15, the lower edges of these walls having a concavecontour indicated at 16, while the upper edges of the walls are ofconvex shape as at 11. A resonant wooden top wall 18 is secured betweenrespective top edges of the side walls, the top wall being so shaped asto lie flush within the top edges of the side walls, so as to form acontiguous convex siir= face.

A concave bottom wall 19 is suitably secured between the wall H, theside walls I4 and the lower edge of the convex top wall I8 so as toenclose the vibrator unit within the housing thus provided.

The vibrator unit includes a motor conven tionally shown at 20 forrotating a shaft 21. The motor is controlled through a suitable switch22 and receives electrical energy through a conductor 23, the latterhaving a plug 24 for insertion into an outlet of a source of current.

Upon the shaft 2| there is secured my improved rotor 25, shown inFigures 4 to 6, consisting of a body member having two right angularlydisposed legs 21, these legs being of the same length and crosssectional area. The body is formed from metal and the legs 21 are anintegral part thereof and connected with each other by a flat portion 28of the body. As best seen in Figure 4, a tapped bore 29 is formed in thefiat portion 28 disposed medially of the legs 21, the bore 29intersecting an opening 30 for reception of the motor shaft 2!. A setscrew 3| engaged through the bore 29 will impinge upon the shaft 2| andthus secure the rotor to the shaft.

By reason of the fact that the legs 21 are at right angles to shaft 21 aforce is exerted over one quarter of the circle described by the rotorunder rotation, the force being distributed over a larger surface of thebody undergoing treatment, the force further being amplified by reasonof the mounting of the vibrator unit within the housing constructed ofresonant wooden walls.

It will be apparent that by constructing the housing with convex andconcave walls, various portions of the human body may be treated. Forinstance, the concave portion I6 will readily accommodate the abdomen,head, and other curved portions of the body, while the convex wall I8will permit treatment of the arms and legs of a patient.

While I have shown and described a preferred form of the device, this isby way of illustration only, and I consider as my own all suchmodifications as fairly fall Within the scope of the appended claims.

I claim: I

1. A therapeutic vibrator comprising a housing, a motor mounted withinand on a .Wall of said housing and said motor having an unbalancedrotor, said housing being formed from resonant wooden material wherebyto amplify impulses produced by said rotor under rotation thereof.

2. A therapeutic vibrator comprising a housing having a vertical wall, aconcave wall and a convex wall, a motor mounted in the housing and onthe vertical wall, said motor having an unbalanced rotor, and means foractuating said motor.

3. A therapeutic vibrator comprising a housing having a flat verticalwall, a concave bottom wall, a convex top wall, and flat side Walls allof said walls being formed from a resonant wooden material, an electricmotor mounted in said; housing and on said vertical wall and having arotary shaft, and a rotor fixed to said shaft and comprising a bodymember having right angularly disposed legs of equal length and crosssectional area.
